Bow string wear from arm guard

[BriBri]

I recently had my bow re-strung, and I noticed that the section of the string that contacts my arm guard when I shoot is beginning to fray slightly. The fabric on the arm guard is quite course - I believe it is some kind of nylon/polyester, and it is wrapped tightly around the staves. So, there is no "give" to the arm guard.

I have seen other materials used on arm guards, from fleece-like material to nylon (but with some padding underneath). I wonder if any of these would alleviate the wear on the bow string whe the string hits it.

Anyone have similar experience with this, and/or can provide me with some recommendations?
